3 Select electric connection based on the draw-ings on page 2
4 Open parameter o61 and set the electric con-nection number in it
5 Now select one of the preset settings from the table on the right-hand side
6 Open parameter o62 and set the number for the array of presettings
7 Open parameter r12 and start the regulation
8 Go through the survey of factory settings. Make any necessary changes in the respective parameters.
9 For network. a. Set the address in o03 b. Start scan function in the system unit.
